ALBERT CEMENTING MACHINE Filed March 16, 1951 5Sheets-Sheet 3 l IL! vi i: ii ins 9 .8 an mN M m a Bu 1 W ans upper endsof which are forked as at 26 to receive trunnions 27 extending inopposite directions from the hopper 28. Thus the hopper is suspendedwith its small or lower end supported between the rollers 5 and 10 andnormally out of contact with them. That face of the hopper nearestroller 5 has an outletzopening 29 extending-throughout the width thereofat the lower end of the hopper and this opening is closed at the bottomby a strip 30 formed of rubber or the like which has a scraping edge 31adapted to be supported close to the roller.

A slide 32 is mounted in the hopper and is adapted to be raised andlowered by means of a handle 33 after which it can be held by a setscrew 34 or the like. The: lower edge and adjacent side portions ofslide 32 can be provided with a lip 35 of rubber or other suitableflexible material for sealing the edge portions of the slide at theoutlet. By raising and lowering the, slide the size of the outlet in thehopper 28 can be varied.

The top of the hopper is adapted to be tightly closed by means of acover 36 so as to exclude air. This cover may support a guide roller 37.The guide roller is preferably located adjacent to the back end of the Iing cam 38 the thickness of the film ofad-1 cover.

' A cam 38 is rotatably mounted between the plates 2 and is adapted tobe shifted by a lever 39. Under normal conditions the container 28 isbalanced by the standards 25 and spaced from the roller 5. By shifting.

lever 39, however, the cam 38 can be'caused to press against'the lowerportion of hopper orcontainer 28 and force the outlet opening toward thesurface of roller 5 with the edge 31' of the rubber strip 30 locatedeither in contact with or at any desired distance from the roller. Thusan adhesive contained in the hopper can gravitate to the surface of theroller and be drawn downwardly there'- by, the amount of adhesiver'eleasedbeing regulated by, the sliding valve 32. By shifthesive on therollercan be variedat will. Surplus adhesive will of course be stoppe bythe edge 31 of strip 30.

Side plates 40 are mounted on the base 1 at points remote from theplates 2 and mounted in them are bearings 41 carryingthe shaft 42 of afeed roller 43. This roll-.

and transmits motion through a chain 49 to a sprocket 50 on shaft 7,Shaft 13 is driven by a chain 51 mountedonsprockets' 52 and; 53 securedtotheshafts 16 and 13 respectivewhich is adaptly. An electric motor orother suitable power device indicated generally at 54 is adapted totransmit motion through worm gearing 55 to a shaft 56 which, in turn,transmits motion through sprocket 57 and chain 58 to a sprocket 59 onshaft 16.

In practice a backing; board B of: any

suitable material is placed onv the base 1 and positioned so as to bearlaterally against a chan' 'neled guidemember 6O interposed between-"oneof the*plates 2 and one of the plates p This board will be gripped bythe teeth "12 on roller 10 and as the gearing heretofore describedconstitutes a reduced speed gearing the backing board will be movedslowly under the rollers 10; 5 and 11.

As it passes under roller 5; an adhesive will be applied thereto 1 fromthe surface 6 -of.

where it is supported by a guide roller37 The forward free end of thisstripmCis' placed on the surfaceof the advancingbackmg strip to whichadhesive has been applied and the two strips, with the adhesive betweenthem, are then passed under roller 43 which will force them tightlytogether and feed them forwardly. 4

The teeth 12 on roller 11 insureqpositive ejection of the'backing stripafterit leaves the roller 5 and the grippingoaction of roller 43 insurespositive delivery. of. all. portions. of the joined strips. f T

(The teeth or studs ,on the several rollers will, bite into the boardbeing. treated. Thus the surface of the board. is, roughenedjand theadhesive will become more :firml'y anchored to the'board thanwouldotherwise,

be possible. Consequently this method ofv applying the adhesive issuperior to the-one in which the adhesive is applied by hand.-

In additionto the guide strips 60, one or;

more guide {blocks 61 can be -adjustably mounted on the-base 1 adjacenttoonegedge of the backing strip, each of these blocks preferablycarrying a pin 62 or Ethe like adapted to be seated in any one ofaseries of recesses .63 in the base.) A finger 64,-is

carried. by each pin for adjustment against the adjacent side edgeof thebacking strip B so as to properly guide it.

What is claimed is: I 1

1. A machine forassembling theplies %of laminated boards including.toothed I roller for feeding one ply of the boardjan'd formingindentations in onesurface thereof, a, contalner having an outlet foradhesive,

means for-transferring adhesive fromthe outlet of the container to coatthe said ply 5 and fill the indentations; means on the coni tainer formovably supporting a second ply and maintaining the container normallyin a pretermined position, and means for guiding said second ply ontoand pressing it y upon the coated and indented surface of the other ply.I v v 2. The combination with a base for supporting the lower ply of alaminated board, and a toothed roller for sliding said ply along thebase and forming indentations in the top surface thereof, of a tiltablecontainer for adhesive having abottom outlet, means for transferringadhesive from the outlet to coat the lower ply and fill the invdentations, means on the container for mov ably supporting an upper plyto maintain the outlet normally in a predetermined position relative tothetransferring means, and rotatable means for pressing the top ply ontothe lower ply and deliveringboth plies from the machine with theindentations concealed therebetween; a

In testimony that I claim the foregoing as myoWn, I have hereto aflixedmy signature GEORGE G. ALBERT!
